1. Introduction
Many people, including me, would like to run Linux on a PCI-based
machine. Since it is not obvious which PCI motherboards and PCI cards
will work with Linux and which do not, I conducted a survey and spent
some hours to compile the information contained herein. Most of this
was done before 1997 and more uptodate technology might be covered in
the device specific howtos such as the XFree86, Xinerama, Networking
and Hardware-HOWTO.
If you have information to add, please mail me. If you have questions,
feel free to ask.
Help with my style/grammar/language is welcome as well. I am not a
native- speaker of English and expect to make occasional mistakes.
Note: "on-board chip" refers to a SCSI chip integrated onto the
motherboard rather than on a PCI expansion card.
Also, "quotes" herein may have slight context editing.
2. Why PCI?
2.1. General overview
The PC-architecture has several BUS-Systems to choose from:
ISA
16 or 8bit, cheap, slow (usually 8Mhz), standard, many cards
available>
EISA
32bit, expensive, fast, few cards available, fading>
MCA
32 or 16bit ex-IBM-proprietary, fast, becoming rare>
VESA-Local-Bus
32bit, based on 486 architecture, cheap, fast, many cards
available>
PCI-Local-Bus
32bit (64 bit coming), cheap, fast, many cards available,
nowadays standard>
MCA worked fine, but never achieved much market, being used on only
some early IBM PS/2 machines. There were very few cards.
EISA was reliable, but rather expensive, and intended more for
servers, than for the average user. It has the next fewest cards
available.
VESA-Local-Bus (VLB) had some problems with high bus-speeds, and was
not very reliable, but mainly due to its low price and better-than-ISA
performance, sold very well. Technically, it's almost a direct map of
the 486 processor bus. Most VESA boards should be stable by now. At
the beginning of 1996, many 486 motherboards still support VESA, but
PCI is growing. VESA busses are tied directly to the speed of the
memory bus for 486's, or half the speed for Pentiums.
PCI now has the advantage. Like EISA it is not proprietary. It is as
faster than EISA or MCA, and cheaper. Most current Pentium
motherboards use the PCI bus; VESA is fading. Virtualy all PCI
motherboards and cards sold at the beginning of 1996 are 32 bit, and
run at 0-33 MHz.
Currently, most Pentium motherboards run the PCI bus at 1/2 the memory
speed (ie: 33 MHz for the 66 MHz memory bus on the P66,P100,P133,P166;
30 MHz for the 60 MHz memory bus on the P60,P90,P120,P150; and 25 Mhz
on the 50 MHz memory bus of the P75). This is probably true of Cyrix
6x86 motherboards too. NexGen 5x86 implemention isn't known. The PCI
spec does allow the PCI bus to be run asynchronously from the
processor, (eg: 33 Mhz bus on P75), but this is not common yet.
PCI 2.1 has been defined, allowing 64 bit PCI, and/or 0-66 MHz
operations, but no x86 chipsets yet support these options. 64 bit PCI
will probably appear first, in 32/64 bit dual compatible versions.
That is, you will be able to mix 32 and 64 bit cards. 66 MHz PCI will
take longer, as it's technically demanding, can only support one or
maybe two slots per bridge, and may not work well with 33 MHz cards.
PCI is not processor dependent like the VESA Local-Bus. This means you
can use the winner-1000-PCI in an Alpha-driven-PCI computer as well as
in a i486/Pentium-driven PCI computer, with the appropriate BIOS and
software. Beside Intel and DEC Alpha platforms, PCI is used on some
PowerPC's.
Some PCI variations to be aware of: some implementations support "Bus
Master" cards in all PCI slots, some in only one slot, and some not at
all; some implementations support "bridging" on cards and some do not.
2.2. Performance
taken from Craig Sutphin's early Pro-PCI-Propaganda
Unlike some local buses, which are aimed at speeding up
graphics alone, the PCI Local Bus is a total system solu­
tion, providing increased performance for networks, disk
drives, full-motion video, graphics and the full range of
high-speed peripherals. At 33 MHz, the synchronous PCI Local
Bus transfers 32 bits of data at up to 132 Mbytes/sec. A
transparent 64-bit extension of the 32-bit data and address
buses can double the bus bandwidth (264 Mbytes/sec) and
offer forward and backwards compatibility for 32 and 64-bit
PCI Local Bus peripherals. Because it is processor-indepen­
dent, the PCI Local Bus is optimized for I/O functions,
enabling the local bus to operate concurrent with the pro­
cessor/memory subsystem. For users of high-end desktop
PC's, PCI makes high reliability, high performance and ease
of use more affordable than ever before; no trivial task at
33 MHz bus-clock rates. Variable length linear or toggle
mode bursting for both reads and writes improves write
dependent graphics performance. By comprehending the loading
and frequency requirements of the local bus at the component
level, buffers and glue logic are eliminated.
See the chapter about Benchmarks for some crude (and perhaps
meaningless) benchmarks on ASUS PCI Boards with 486 and 586.
2.3. The onboard-SCSI-II-chip NCR53c810
One very nice feature of some PCI mother boards is the NCR onboard-
SCSI-II-chip, which is said to be as fast as the EISA-Adaptec-1742,
but much cheaper. Drivers for DOS/OS2 are available. Drew Eckard has
released his version of his NCR53c810-driver, which is in the standard
kernel since v1.2.
This works so well I sold my adaptec-1542B-ISA soon after I bought the
ASUS SP3-saturn-chipset II PCI board, and found the onboard NCR-SCSI
controller to be much faster.
The NCR53c810-chip is onboard on some PCI-motherboards. There are
add-on-boards available too, for about US$ 70.00.
There is only one thing I noticed did not work with the NCR-drivers
when I tried them. Disconnect/Reconnect did not work, so using a SCSI-
tape could be a pain, especially when using "mt erase" or the like
blocks the whole SCSI-bus until it has finished. Since this was very
unsatisfying for me, I bought one of these nice but expensive DPT PCI
SCSI controller and had no such problems anymore.
People have reported this problem has been solved by Drew by now.
FreeBSD does support the NCR53c810 for quite a long time already,
including Tagged Command Queues, FAST, WIDE and Disconnect for NCR
53c810, 815, 825. Drew said, it would be possible to adapt the FreeBSD
driver to Linux. I somewhere saw some patches to do exactly this, any
pointer to the location?
I personaly have the impression there are some important wheels
invented more than once because of the differently evolving of FreeBSD
and Linux. Some more cooperation could do both systems very well...
2.4. Drew Eckhardt on PCI-SCSI:
Drew said on end of March 95 about the SCSI on PCI: (slightly edited
for clarity in context)
The Adaptec 2940, Buslogic BT946, BT946W, DPT PCI boards, Future
Domain 3260, NCR53c810, NCR53c815, NCR53c820, and NCR53c825 all work
for some definition of the word works.
· The Adaptec 2940 suffers from the same cabling sensitivity that
plagues all recent boards, but otherwise works fine.
· The Future Domain boards are not busmasters, and the driver doesn't
support multiple simultaenous commands. If you don't (currently)
need multiple simultaneous commands, get a NCR board, which will be
cheaper and is busmastering. If you need multiple simultaneous
commands, get a Buslogic.
· The Buslogic BT956W will do WIDE SCSI with the Linux drivers
(although you can't use targets 8-15), the Adaptec 2940W (with one
line patch to the 2940 driver) won't, nor will the NCR53c820 and
NCR53c825.
· The NCR boards are dirt cheap (< $ 70 US), are generally quite
fast, but the driver currently doesn't support multiple
simultaenous commands. Alpha which do neat things like
disconnect/reconnect and synchronous transfer are now publicly
available, see below.
· Emulux, Forex, and other unmentioned PCI SCSI controllers will not
work.
2.5. New Alpha Version of the NCR driver
Well, this is not exactly *that* new anymore, please try to he
versions which are in the kernel by version 2.0.x before going for
this entry.
Alpha versions of the NCR driver which do neat things like
disconnect/reconnect and synchronous transfers are now publically
available. Any one interested in playing with them should
· Join the NCR mailing list, by sending mail to
majordomo@colorado.edu with subscribe ncr53c810 in the text.
· Get all of the readmes, and latest diffs file from
ftp://tsx-11.mit.edu/pub/ALPHA/linux/SCSI/ncr53c810
2.6. The EATA-DMA driver and the PCI SCSI controllers from DPT
The EATA-DMA scsi driver has undergone extensive changes and now also
supports PCI SCSI controllers, multiple controllers and all SCSI
channels on the multichannel SmartCache/Raid boards in all
combinations of WIDE, FAST-20 (ULTRA) and DIFFERENTIAL.
The driver supports all EATA-DMA Protocol (CAM document CAM/89-004
rev. 2.0c) compliant SCSI controllers and has been tested with many of
those controllers in mixed combinations.
Those are: (ISA) (EISA) (PCI)
DPT Smartcache: PM2011 PM2012B
Smartcache III: PM2021 PM2022 PM2024
PM2122 PM2124
PM2322
Smartcache IV: PM2041 PM2042 PM2044
PM2142 PM2144
PM2322
SmartRAID : PM3021 PM3122
PM3222 PM3224
PM3334
and some controllers from NEC, AT&T, SNI, AST, Olivetti and Alphatronix.
On a "base" DPT card (no caching or RAID module), a MC680x0 controls
the bus-mastering DMA chip(s) and the SCSI controller chip. The DPT
SCSI card almost works like a SCSI coprocessor.
The DPT card also will emulate an IDE controller/drive (ST506
interface), which enables you to use it with all operating systems
even if they don't have an EATA driver.
On a card with the caching module, the 680x0 maintains and manages the
on-board cacheing. The DPT card supports up to 64 MB RAM for disk-
cacheing.
On a card with the RAID module, the 680x0 also performs the management
of the RAID, doing the mirroring on RAID-1, doing the striping and ECC
info generation on RAID-5, etc.
The entry level boards utilize a Motorola 68000, the high-end, more
raid specific DPT cards use a 68020, 68030 or 68040/40MHz processor.
Official list prices range from $ 265 to $1.645 (January 18, 1996)
Since I've been asked numerous times where you can buy those boards in
Europe, I asked DPT to send me a list of their official European
distributors. Here is a small excerpt:

"IMHO, the DPT cards are the best-designed SCSI cards available for a
PC. And I've written code for just about every type of SCSI card for
the PC. (Although, in retrospect, I don't know why!) ;-)" Jon R.
Taylor (jtaylor@magicnet.net) President, Visionix, Inc.
The latest version of the EATA-DMA driver and a Slackware bootdisk is
available on: ftp.i-Connect.Net:/pub/Local/EATA
Since patchlevel 1.1.81 the driver is included in the standard kernel
distribution.
The author can be reached under these addresses: neuffer@mail.uni-
mainz.de or mike@i-Connect.Net
2.7. BT-946C fully supported with kernel 1.3.x and newer
There is a driver in the 1.3.x kernels (available as a patch for the
1.2.13 kernel) written by someone associated with buslogic that fully
supports the 946C and ALL of it's features including strict round
robin, tagged queueing, multiple scatter/gather, multiple mailboxes,
IRQ sharing, and yes, 15 devices on Fast/Wide. It is no longer
necessary to use any ISA emulation with the driver (no DMA channel, no
ISA address), and the driver is /fast/ and /stable/ (it's out of BETA
and into full release).
The driver is available on ftp.dandelion.com (the newest version can
always be got by doing "get BusLogic*"). It supports ALL BusLogic
controllers with the exception of the FlashPoint LT, which uses a
different interface. The driver is included in the 1.3.x kernels as
standard for BusLogic devices.
2.8. Future Domain TMC-3260 PCI SCSI
Rik Faith (faith@cs.unc.edu) informed me on Wed, 1 Feb 1995 about the
Future Domain TMC-3260 PCI SCSI card being supported by the Future
Domain 16x0 SCSI driver. Newer information might be contained in the
SCSI-HOWTO.
· Detection is not done well, and does not use standard PCI BIOS
detection methods (someone who has a PCI board needs to send me
patches to fix this problem). So, you might have to fiddle with
the detection routine in the kernel to get it detected.
· The driver still does not support multiple outstanding commands, so
your system will hang while your tape rewinds.
· The driver does not support the enhanced pseudo-32bit transfer mode
supported by recent Future Domain chips, so you will not get
transfer rates as high as under DOS.
· The driver only supports the SCSI-I protocol, so your really fast
hard disks will not get used at the highest possible throughput.
(Again, fixes for all these problems are solicited -- no one is
working on them at this time.)
2.9. other thoughts on scsi
James Soutter (J.K.Soutter1@lut.ac.uk) asked me to add the following
information on Fast-Wide-SCSI-2:
Fast Wide SCSI-2 is sometimes incorrectly called SCSI-3. It
differs from the normal Fast SCSI-2 (like the Adapted
1542B?) because it uses a 16 bit data bus rather than the
more usual 8 bit bus. This improves the maximum transfer
rate from 10 MB/s to 20 MB/s but requires the use of special
Fast Wide SCSI-2 drives.
The added performance of Fast Wide SCSI-2 will not
necessarily improve the speed of your system. Most hard
disk drives have a maximum internal transfer rate of less
than 10 MB/s and so one drive alone can not flood a FAST
SCSI-2 bus.
In Seagate's Oct 1993 product overview, only one Fast Wide
SCSI-2 drive has an internal transfer rate of more than 10
MB/s (the ST12450W). Most of the drives have a maximum
internal transfer rate of 6 MB/s or less, although the
ST12450W is not the only exception to the rule. In
conclusion, Fast Wide SCSI is designed for the file server
market and will not necessarily benefit a single user
workstation style system.
Rather than buying a PCI system with a SCSI interface on the
motherboard, or rather than waiting for the NCR driver, you
could purchase a separate PCI based SCSI card. According to
Drew, the only PCI SCSI option that stands a chance of
working is the Buslogic 946. It purports to be Adaptec 1540
compatible, like the EISA/VESA/ISA boards in the series.
Drew commented that other PCI based SCSI controllers are
unlikely to be supported under Linux or the BSD's because
the NCR based controllers are cheaper and more prevalent.
I definitly recommend reading the SCSI HOWTO in regards to newer
information about PCI SCSI drivers.
Ernst Kloecker (ernst@cs.tu-berlin.de) wrote: (edited)
Talus Corporation has finished a NS/FIP driver for PCI
boards with NCR SCSI. It will be shipping very soon, might
even be free because a third party might pay for the work
and donate the driver to NeXT.
Not every PCI-Board has got the chip. The old ASUS do, and one of the
J-Bond boards does, too. (Most of the boards nowadays (6/95) do expect
you to buy the NCR53c810 seperately.) Some vendors provide an
alternative as you can read in Drew's text...
The NCR-Chip is clever enough to work with drives formatted by other
controllers, and should be no problem.
3. ASUS-Boards
3.1. ASUS and the NMI (Parity) -- impact on Gravis-Ultrasound
The newer trition PCI-Mainboards in 1995 did not seem to support
parity-SIMMS anymore. Since I usualy took the cheaper nonparity-SIMMS
anyway, I did not consider this a problem until I put the Gravis-
Ultrasound into my machine. Under DOS the SBOS-Driver and Setup/Test
utility does complain about "nmi procedure disabled on this p.c.". The
manual says I'd better get a better mainboard in that case, not very
helpful.
The gravis-ultrasound did work nice in the ASUS-SP3 and ASUS-SP4,
inspite of this, but the gravis-ultrasound-max I have here got gmod to
kernel panic on both boards, and sometimes when playing au-files via
/dev/audio did strange things, like playing the rest of an older,
previously played sound after the new one. The sounddriver does
recommend a buffer of 65536 with the GUS Max instead of the small one
like the GUS - why I do not know. I do not have such a problem with
the newer ASUS TP4 XE boards, though. Both are equipped with 1M DRAM
onboard. These problems are probably not related to the NMI-problem,
but because of the sounddriver?
I heard not only ASUS but most of the newer PCI-Mainboards are lacking
in parity/NMI-support.
Strange enough - the ASUS-TP4 (Trition Chipset) does work with the GUS
Max - it does load the SBOS-Driver. I have to admit, I am confused.
3.2. Various types of ASUS Boards
3.2.1. ASUS SP3 with saturn chipset I (rev. 2) for 486,
· 2 x rs232 with 16550
· NCR53c810 onboard,
· slightly broken saturn-chipset I (rev. 2)
3.2.2. ASUS SP3G with saturn chipset II (rev. 4) for 486,
like SP3, but less buggy saturn chipset
3.2.3. ASUS SP3-SiS chipset, for 486
like AP4, but newer, SiS chipset, green functions and all the EIDE,
rs232 with 2 16550 and centronics. Only 2 SIMM Slots, Does seem to
work with AMD486DX4/120, but was not very reliably on NCR53c810 and
various operating systems (Windows-NT, Windows95, OS2), after
upgrading to a PentiumBoard ASUS SP4, all the problems vanished, so it
must have been the board. Still does seem to work nice for Linux,
though.
3.2.4. ASUS AP4, for 486, with PCI/ISA/VesaLocalbus
green functions, 1VL, 3 ISA, 4 PCI slots, only EIDE onboard, no fd-
controller, no rs232/centronics. Very small size.
does recognice AMD486DX2/66 as DX4/100 only. This can be corrected
with soldering one pin (which?) to ground, but I would not recommend a
board like this anyway.
The one I tested was broken for OS2 and Linux, but people are said to
use it for both.
The VesaLocalbus-Slot is expected to be slower than the normal vesa-
localbus boards because of the PCI2VL bridge, but without penalty to
the PCI section.
3.2.5. ASUS SP4-SiS, for Pentium90, PCI/ISA
like SP3-SiS, but for Pentium90/100.
3.2.6. ASUS TP4 with Triton chipset and EDO-Support
has the Triton-Chipset for better performance and supports normal
PS2-Simms as well as Fast-Page-Mode and EDO modules.
3.2.7. ASUS TP4XE with Triton chipset and additional SRAM/EDORAM sup­
port
supports the new EDORAM and upcoming SRAM standards. At least SRAM is
said to considerabely increase performance. Did for some reason not
accept the 8M PS2-SIMMS working ok in ASUS SP4, after changing them
against others, bigger looking ones, (16 chips instead of 8 if I
remember right) it worked ok. Has been tested with P90 and P100.
3.2.8. ...and many others now.
if you have new information on problems with them, please report.
3.3. Benchmarks on ASUS Mainboards
I tried to compare the speed of CPUs in two ASUS Mainboards: for 486 I
tested the SP3 SiS (the one with one vesa-local-bus slot) and for 586
I tested the ASUS TP4/XE, each with 16M RAM, always the same unloaded
system with another CPU, with whetstone and dhrystone.
I must admit, I have not read the benchmarks-faq yet, and will
probably edit the section a loot soon. If you have any comments,
please mail me.
I am especially confused about the amd486DX4/100 being faster on
dhrystones than the DX4/120 version? I did not see that kind of
inconsistency on comparing the P90 and P100.
Perhaps this was at fault: when I plugged in the amdDX4-100, I had the
board jumpered for DX2-66. While the BIOS did report it as an DX4-100,
the board might have used the wrong clockspeeds... but since DX2-66
uses 33Mhz * 2 and DX4 uses 33Mhz * 3, this would have been correct?
The board running with DX4-120 is jumpered to 40Mhz * 3 = 120 Mhz.
Another thing I wonder about is why the whetstones-result does yield
so even numbers on some machines?
3.3.1. ASUS SP3 with amd486DX4-100
· Dhrystone time for 500000 passes = 7 by 63559 dhrystones/second
· Whetstone time for 1000 passes = 5 by 200.0000 Whetstones/second
3.3.2. ASUS SP3 with amd486DX4-120
· Dhrystone time for 500000 passes = 8 by 56074 dhrystones/second
· Whetstone time for 1000 passes = 4 by 250.0000 Whetstones/second
3.3.3. ASUS SP3 with intel486DX2-66
· Dhrystone time for 500000 passes = 9 by 50761 dhrystones/second
· Whetstone time for 1000 passes = 7 by 142.8571 Whetstones/second
3.3.4. ASUS TP4/XE with intel586-90
· Dhrystone time for 500000 passes = 4 by 101010 dhrystones/second
· Whetstone time for 1000 passes = 3 by 333.3333 Whetstones/second
3.3.5. ASUS TP4/XE with intel586-100
· Dhrystone time for 500000 passes = 4 by 102040 dhrystones/second
· Whetstone time for 1000 passes = 2 by 500.0000 Whetstones/second
3.4. Detailed information on the old ASUS PCI-I-SP3 with saturn
chipset from heinrich@zsv.gmd.de:
· 3 PCI, 4 ISA Slots (3x16, 1x8 Bit)
· ZIF Socket for the CPU
· room for 4 72pin-SIMMs (max. 128M)
· Award BIOS in Flash-Eprom
· Onboard: NCR-SCSI, 1par, 2ser (with FIFO), AT-Bus, Floppy
The board does like most in that price class -- write-through cache,
no write-back. This should not be significant, maybe 3% of
performance.
The BIOS supports scsi-drives under DOS/Windows without additional
drivers, but with the board come additional drivers which are said to
give better performance, for DOS/Windows(ASPI), OS2, Windows-NT, SCO-
Unix, Netware (3.11 and 4, if interpreted correctly)
Gert Doering (gert@greenie.muc.de) was saying the SCO-Unix-driver for
the onboard-SCSI-Chip was not working properly. After two or three
times doing: "time dd if=/dev/rhd20 of=/dev/null bs=100k count=500" it
kernel-paniced...
The trouble some people experienced with this board might be due to
them using an outboard Adaptec-SCSI-Controller with "sync negotiation"
turned on. (This predates the NCR driver release; hence the use of the
Adaptec.) Please check that in the BIOS-Setup of the Adaptec-1542C if
you use one and have problems with occasional hangups!
There is a new version of the ASUS-Board which should have definitely
less problems. It is called ASUS-PCI-I/SP3G, the G is important. It
has the new Saturn-chipset rev. 4 and the bugs should be gone. They
use the Saturn-ZX-variant and the new SP3G has fully PCI conforming
level-triggered (thus shareable), BIOS-configurable interrupts. It
has an on-board PS/2-mouseport, EPA-power-saving-modes and
DX4-support, too. It performs excellently. If you can get the German
computer magazine C't from July (?), you will find a test report where
the ASUS-Board is the best around.
Latest information about ASUS-SP3-G: You might experience crashes when
using PCI-to-Memory-Posting. If you disable this, all works perfect.
jw@peanuts.informatik.uni-tuebingen.de said he believed it to be a
problem of the current Linux-kernel rather than the hardware, because
part of the system still works when crashing, looking like a deadlock
in the swapper, and OS2/DOS/WINDOZE don't crash at all.
Someone else with a very old ASUS-SP3 (saturn-I chipset) reported
crashes with using XFree86, which went away when he installed the very
latest betaversion which seems to work around a bit of the problems.
3.5. Pat Dowler (dowler@pt1B1106.FSH.UVic.CA) with ASUS SP3G
· ASUS SP3G board (it is rev.4 == saturn II)
· AMD DX4-100 CPU (need to set jumper 36 to 1&2 rather than 2&3,
otherwise it's set the same as other 486DXn chips)
· 256K cache (comes with 15ns cache :-)
· 16meg RAM (2x8meg)
· ET4000 ISA video card
· quantum IDE hard drive
· SMC Elitel16 combo ethernet card
Unlike some other reports, I find the mouse pointer moves very smoothy
under X (just like the ol' 386) - it is jumpy under some, but not
all, DOS games though...
Performance is great!! I ran some large floating point tests and found
the performance in 3x33 (100MHz) mode to be almost 1.5x that in 2x
(66MHz) mode (large being 500x500 doubles - 4meg or so)... I was a
little dubious about clock-tripling but I seem to be getting full
benefit :-)
The heavily configurable energy star stuff doesn't work with the
current AMD DX4 chips - you need an SL chip
I really need a SCSI disk and a PCI video card :-)
(I had a phonecall by a person who had this problem with the buggy SMC
FIFO chipset, after using X-window they hung.)
4. confusion about saturn chipsets
Pat Duffy (duffy@theory.chem.ubc.ca) said:
Saturn I: these are revisions 1 and 2 of the Saturn chipsets.
Saturn II: This is also called rev. 4 of the Saturn chipsets.
As far as I know, rev. 3 never actually shipped, and (from a few people who
have it) the SP3G now has rev. 4 (or Saturn II) in it.
Confused? Well, the only real definitive answer is to get ahold of the board
and run the debug script in the PCI chipset list on it. As far as I know,
though, the SP3G board is indeed shipping with rev. 4 (Saturn II).
5. Video-Cards
Linux people have successfully used # 9 XGE Level 12, ELSA Winner
1000, and S3-928 video cards. The XFree86(tm)-3.1.1 does support
boards with the tseng et4000/w32 in accelerated mode, as well as S3
Vision 864 and 964 chipsets including boards like the ELSA Winner
1000Pro and 2000Pro, Number Nine GXE64 and GXE64Pro, Miro Crystal
20SV). Support in the S3 Server for the Chrontel8391 clock chip has
been added.
Trio32 and Trio64 S3 Boards like the SPEA V7 Mirage P64 PCI and MIRO
Crystal 40SV, are also supported, the Mach32 and Mach64 are supported
in accelerated mode, too.
The SVGA Driver
16bpp mode (65K colors instead of the usual 256) support for Mach32
boards as well as 32bpp for some S3 boards and the P9000 boards has
been added.
tldraben@teleport.com reported:
· Diamond Stealth W32 (et4000/W32) -- Text mode works, X11 suffered
from "pixel dust", unbearable never got it to work and returned it.
· # 9GXE L12 -- Works, virtual consoles corrupted when switched,
fixed this with disabling the "fast dram mode" feature in his BIOS.
Does not get a dot clock above 85, though.
Genoa Phantom 8900PCI card seems to work well. Genoa Phantom/W32 2MB
does not work in an ASUS-Board. Tseng 3000/W32i chipset seems to work
well. Spea-v7 mercury-lite works perfectly since XFree86(tm)-2.1.
Spea V7 Mirage P64 PCI 2M with Trio64 works nice since
XFree86(tm)-3.1.1
ATI Graphics Ultra Pro for PCI with 2MB VRAM and an ATI68875C DAC run
well as dem@skyline.dayton.oh.us tells us: "It's humming right along
at 1280x1024 w/256 colors @74Hz non-interlaced. Looks great."
Paradise WD90C33 PCI did lock up on screensaver/X - this has been
solved in the newer versions of the kernel. jbauer@badlands.NoDak.edu
(John Edward Bauer)
miroChrystal 8S/PCI (1MB) S3 - no problem.
Stephen Tweedie reported his Cirrus Logics 5434 PCI card works well.
It is a 64bit with 2M and runs perfectly with the SVGA driver in 8, 16
and 32 bit per pixel.
6. Ethernet Cards
Of course the ISA-ethernet-cards still work, but people are asking for
PCI-based ones. The author of many (if not most) ethernet- drivers
said the following some time ago (unfortunately I have not managed to
contact him about new information):
From: Donald Becker (becker@cesdis.gsfc.nasa.gov) Subject:
PCI ethernet cards supported?
The LANCE code has been extended to handle the PCI version.
I hope to get the PCI probe code (about a dozen extra lines
in the LANCE driver) into the next kernel version. I'm
working on the 32 bit mode code. I haven't yet started the
21040 code.
I'll write drivers for the PCnet32 mode and the DEC 21040.
That will cover most of the PCI ethercard market.
file://cesdis.gsfc.nasa.gov/pub/people/becker/whoiam.html
In the new testkernels of 1.1.50 and above, the AMD-singlechip
ethernetadapters are supported. With a pentium, they ought to then see
900K/second ftps +(assuming an NCR PCI scsi controller) at about 20%
cpu load. (AMD Lance).
Anything based on the AMD PCnet/PCI chip should work at the time
being. In the US the Boca board costs under US$ 70
Geoffry Coram reported in the news that he got his 3com 590 TPO to
work. He had to get the alpha driver from
http://cesdis.gsfc.nasa.gov/linux/drivers. Other drivers would be
there as well. Note
http://cesdis.gsfc.nasa.gov/linux/drivers/vortex.html
Donald Holmgren said he successfully attached his DEC DE435 (PCI) card
to the local network on thin coax (BNC). The DE435 driver checks the
twisted pair connection first, then switches to the alternate port
(jumper selectable as AUI or BNC) if the 10BaseT port fails.
Jim Cusick uses the Boca BEN 1PI card on a thin coax network. It
works just fine. You might want to check out:
http://cesdis.gsfc.nasa.gov/linux/misc/boca-failure.html for details
on the early failures of this card. My second card, after sending one
back for replacement, was marked "PN 4186". The old one that did not
work was "PN 4185". Mandate this newer model when you order from you
vendor. At $ 70, the card is a good deal.
Dave Platt recommends to stay off the Boca BEN1PI card at all costs.
It would be unreliable due to design flaws, and Boca seems unable to
really fix the problem. The 3Com 3c590 "Vortex" PCI card is available
in a combo version (10BaseT, thin coax, and AUI). The Linux driver
for this card is not yet part of the release kernel, but is available
from http://cesdis.gsfc.nasa.gov/linux/drivers/vortex.html and can be
patched into the later 1.2.x kernels (as well as 1.3.x) without much
difficulty. The Linux driver does not support the interface
autodetect feature of this card - you must use the DOS utility to
configure the card for the interface you wish to use (thin coax in
this case). Once you've done that, the Linux driver will use the
correct interface.
He has been using a 3c590 for several weeks, and it is working fine.
Dave Kennedy said he got two of the above Boca boards and they work
fine under light load, but under heavy work like ftping two 16M files
into both directions, they failed. He sent the boards back to Boca for
a hardwarefix. After they soldered a couple of things
(diodes/resistors) onto the card and sent them back, the cards worked
fine regardless of load. The two cards have been in 7/24 use in two
P90 systems without problems for 6 months now.
Craig does not recommend it since Boca seems not to follow the AMD
specs but he has been running them for 2 weeks without problems. He
tested his NFS performance and has been moving large files to and from
server (16M, 8M). He also tried to do all his workin localy using his
data files mounted by NFS and has had no problems. Performance seems
to be 100 percent better (wrt to NFS performance) over his NE2000 ISA
board. (editors note: but so would probably have been the ISA SMC
Elite Ultra?)
6.1. 3com-3c590-tpo
Someone on usenet mentioned ht used the 3Com-3C590-TPO (EtherLink III
- PCI). He had to get the "3c59x.c" driver and "vortex.patch" to make
it work with his 1.2.8 Linux kernel.
6.2. DEC435 PCI NIC
The DEC435 PCI NIC is said to work great with the drivers included in
the Slackwaredistribution - I'd say they are in the standard-kernel?

drives power down and up properly without panics. The system is 24hrs
up a day and still running. Kernel compilation takes between 5 and 7
minutes, depending on options.
8.2. California Graphics - Sunray II Pro
Guido Trentalancia (guido@gulliver.unian.it) reported the California
Graphics - Sunray II Pro with Triton chipset to work well with
Pentium100, Hd: Conner cfs420a, Conner cfs210a, crunching numbers at
147492 dhrystones/second.
8.3. Micronics P54i-90 (root@intellibase.gte.com)
Pentium with 90Mhz, 32M RAM and 512K L2-cache. Works extremely well (a
kernel recompile takes 10 minutes :-).
The board includes:
· UART - two 16550A high speed UARTS
· ECP - one enhanced parallel port
· Onboard IDE controller
· Onboard floppy controller
Pros: Currently, I'm using it with an Adaptec 1542CF and a 1G Seagate
drive, No problems. Graphics is ATI Graphics Pro Turbo (PCI). Very
fast. The serial ports can keep up with a TeleBit T3000 modem (38400)
without overruns. Caching above 16M does occur. There are 3 banks of
SIMM slots (2 SIMM's per bank), with each bank capable of 64M each (2
32M 72-pin SIMM's). Each bank must be filled completely to be used
(I'm only using bank 0 with 2 16Mx72-pin SIMM's). The CPU socket is a
ZIF type socket. The BIOS is Phoenix, FLASH type.
Drawbacks: RAM is expandable to 192M, but the L2 cache is maxed at
512K. While the graphics are very fast, there is currently no XF86
server for the Mach64 (well, actually there is, but it doesn't use any
of the accelerator features; it's just an SVGA server). I don't know
if the onboard IDE hard drive controller works; I'm prejudiced against
a standard that won't allow my peripherals to operate across
platforms, so I didn't buy an IDE disk; instead, I got a Seagate
31200N and a NEC 3Xi.

8.4. Angelo Haritsis (ah@doc.ic.ac.uk) about SA486P AIO-II:
The motherboard I eventually bought (in the UK) is one supporting 486
SX/DX/DX2/DX4 chips. It is called SA486P AIO-II. Features include:
· Intel Saturn v2 chipset
· Phoenix BIOS (flash eprom option)
· NCR scsi BIOS v 3.04.00
· 256K 15ns cache (max 512) write back and write through
· 4 72-pin SIMM slots in 2 banks
· 3 PCI slots, 4 ISA
· On-board NCR 53c810 scsi controller
· On-board IDE / floppy / 2 x 16550A uarts / enhanced parallel
I bought it from a company (UK) called ICS, (note I have no
connections whatsoever with the company, just a happy customer). I use
a 486/DX2-66 CPU.
Before I had a VLB 486 m/board with a buslogic BT-445S controller that
I was borrowing. I have 2 scsi devices: 1 barracuda 2.1GB ST12550N
disk and a Wangtek 5525ES tape drive. I was expecting a lot of
adventures by switching to the new motherboard, esp after hearing all
these non-success stories on the net. To my surprise everything worked
flawlessly on the 1st boot! (1.1.50). And it has been doing so for
about a month now. I did not even have to repartition the disk:
apparently the disk geometry bios translation of the 2 controllers is
the same. Linux has had no problems at all. SCSI is visibly much
faster as well (sorry, I have no actual performance measurements).
The only problems (related to Drew's linux ncr53c7,810 scsi driver -
thanks for the good work Drew!) are:
· no synchronous transfers are yet supported => performance hit
· disconnect/reconnect is disabled => disk scsi ops "hold" during
certain slow scsi device opeartions (eg tape rewind)
· tagged queuing is not there (?) => performance hit
If you get Windows complainingg about 32-bit disk driver problems,
just disable 32-bit disk access via Control Panel. This should not
hurt performance. (What I did is remove the WDCTRL driver from my
SYSTEM.INI).
All else is fine. I tried the serial ports with some dos/windows s/w
and worked ok. The IDE/floppy work ok as well. I have not tried the
parallel yet. The motherboard is quite fast and so far I am very
pleased with the upgrade. I have not yet tried a PCI graphics board. I
will later on. I am using an old ISA S3 which is fine at the moment.
PS: the NCR drivers in the 2.0.x kernels should have no problems of
that kind anymore. please consult the SCSI-HOWTO for further and
hopefully more uptodate information.

Motherboard - Intel Premiere Plato-babyAT 90mhz with Buslogic bt946c
w/4.86 mcode w/4.22 autoSCSI firmware, (note, mine came with 4.80
mcode and 4.17 autoSCSI firmware. (interrupt pins A,B,C conform to
respective PCI slots!) ATI Xpression (Mach64) - using driver from
sunsite, (running AcerView 56L monitor).
The motherboard has 4 IDE drives, Linux (Slackware 2.0) sees the first
two and everything on the Buslogic as it emulates an adaptec 1542.
Uh, yes, Dos sees them all. Buslogic is VERY accomodating in regards
to shipping upgraded chips (you will have to know how to change PLCC
(plastic leaded chip carrier) chips, 3 of them. Though, don't let
that scare you :-) it's not that tough. Get a low end PLCC removal
tool, and your in business. You also might want to "flash upgrade
your system bios from Intel's IPAN BBS, a trivial process. Whats even
more interesting is I also have a Sound Blaster SCSI-2 running a scsi
CDROM drive off it's adaptech 1522 onboard controller. So thats 4 IDE
drives (2 under Linux) and 2 SCSI-2 controllers.
I hope this helps others who are struggling with PCI technology use
Linux! Jerry (jeromem@xnet.com)
8.13. Timothy Demarest (demarest@rerf.or.jp) Intel Plato Premiere II
My system is configured as follows: 16Mb 60ns RAM, 3Com Etherlink-III
53C809 ethernet card (using 10base2), ATI Mach 64 2Mb VRAM, Toshiba 2x
SCSI CDROM, NCR 53c810 PCI SCSI, Syquest 3270 270Mb Cartridge Drive,
Viewsonic 17 monitor, Pentium-90 (FDIV Bug Free). Running Slackware
2.1.0, Kernel 1.2.0, with other misc patches/upgrades.
Everything is functioning flawlessly. I dont recommend the Syquest
drives. I have used the 3105 and the 3270 and both a very, very
fragile. Also, the cartridges are easily damaged and I have had
frequent problems with them. I am in the process of looking for
alternative removable storage (MO, Zip, Minidisc, etc).
Some information you might need:
8.13.1. Flash Bios upgrades
Flash Bios updates can be ftp'd from
wuarchive.wustl.edu:/pub/MSDOS_UPLOADS/plato. The current version is
1.00.12.AX1. The BIOS upgrades *must* be done in order. 1.00.03.AZ1
to 1.00.06.AX1 to 1.00.08.AX1 to 1.00.10.AX1 to 1.00.12.AX1. The
Flash BIOS updates can also be downloaded from the Intel BBS. I do
not have that number right now.
8.13.2. NCR 53c810 BIOSless PCI SCSI
If you are using an NCR 53c810 BIOSless PCI SCSI card in the Plato,
you may have trouble getting the card to be recognized. I had to
change one of the jumpers on the NCR card: the jumper that controls
whether there is 1 or 2 NCR SCSI cards in your system must be set to
"2". I dont know why, but this is how I got it to work. The other
jumper controls the INT setting (A,B,C,D). I left mine at A (the
default).
8.13.3. apart from that - plug and play!
There are no settings in the motherboard BIOS for setting the NCR
53c810. Dont worry - once the card is jumpered correctly, it will be
recognized! So much for PCI Plug-n-Play!
8.14. heinrich@zsv.gmd.de with ASUS
ASUS-PCI-Board (SP3) having:
· -- Asus PCI-Board with AMD 486/dx2-66 and 16M RAM
· -- Fujitsu 2196ESA 1G SCSI-II
· -- Future Domain 850MEX Controller (cheap-SCSI-Controller, almost a

· -- ATI Graphics Ultra (the older one with Mach-8 Chip, ISA-Bus)
· -- Slackware 1.1.1
He just exchanged the boards, plugged his cards in, connected the
cables, and it worked perfect. He does not use any PCI-Cards yet,
though.
8.15. CARSTEN@AWORLD.aworld.de with ASUS
ASUS-PCI-Board with 486DX66/2, miro-crystal 8s PCI driven by the
S3-drivers of XFree86-2.0, using the onboard SCSI-Chip. No problems
with compatibility at all.

8.18. robert logan (rl@de-montfort.ac.uk with GW/2000)
Gateway 2000 4DX2-66P 16 Megs RAM, PCI ATI AX0 2MB DRAM (ATI GUP). WD
2540 Hard Disk (528 Megs) CrystalScan 1776LE 17inch. (Runs up to
1280x1024) Slackware 1.1.2 (0.99pl15f)
It is giving no problems. He uses SLIP for networking and an Orchid-
Soundwave-32 for niceties, awaiting the NCR-Driver. The only problem
he has is that the IDE-Drive could be much faster on the PCI-IDE. It
is one of the new Western Digital fast drives and in DOS/WfW it
absolutely screams - on Linux it is just as slow as a good IDE-Drive.
8.19. archie@CS.Berkeley.EDU and his friend use ASUS
Archie and his friend have rather similar configurations:
· ASUS PCI-SP3 board (4 ISA, 3 PCI)
· Intel 486DX2/66
· Genoa Phantom 8900PCI card (friend: Tseng 3000/W32i chipset)
· Maxtor 345 MB IDE hard drive
· Supra 14.4 internal modem
· ViewSonic 6e monitor (Archie)
· NEC Multisync 4fge (friend)
· Slackware 1.2.0
The onboard-SCSI is disabled. First there were problems with the IDE-
drive: ``on the board there's a jumper which selects whether IRQ14
comes from the ISA bus or the PCI bus. The manual has an example where
they show connecting it to PCI INT-A. Well, we did that just like the
example... but then later our IDE drive would not work (the IDE
controller is on board). Had to take it back. The guys at NCA were
puzzled, then traced it back to this jumper. I guess the IDE
controller uses IRQ14 or something? That's not documented anywhere in
the manual. Other than that, seems to be kicking ass nicely now.
Running X, modeming, etc. (for the Supra you have to explicitly tell
the kernel that the COM port has a 16550A using setserial (in
Slackware /etc/rc.d/rc.serial))''.
8.20. Michael Will with ASUS-SP3 486 (the old one)
used the following:
· ASUS PCI-SP3-Board with 486dx2/66 and 16M RAM
· NCR53c810-SCSI-II chip driving a 1GB-Seagate-SCSI-II disk and a
Wangtec-tape
· ATI-GUP PCI Mach32 Graphics card with 2M VRAM running perfectly
with XFree86(tm)-3.1 8bpp and 16bpp
· Linux kernel 1.1.69
It runs perfectly and I am content with the speed, the ATI-GUP-PCI
(Mach32) does not give as good benchmarks as expected, though. Since I
got the money by now, I got me an ASUS-SP4 with P90 which gives me
better throughput on Mach32-PCI... If I had even more money I'd get
me another 16M of RAM and a Mach64-PCI with 4M RAM, though... I still
keep on dreaming :-)
8.21. Mike Frisch (mfrisch@saturn.tlug.org) Giga-Byte 486IM
· Motherboard: Giga-Byte 486IM

· PCI Video card: ATI Graphics eXpression PCI 2MB DRAM
· Linux Kernel: 1.2.9
· Linux Dist'n: Highly modified Slackware 2.2.0
I have been running this board 24 hours a day for the past 5-6 months.
It has worked flawlessly for me under DOS/Windows, OS/2 Warp, and
Linux (with Linux being run usually 24 hours a day).
8.22. Karl Keyte (kkeyte@esoc.bitnet) Gigabyte GA586 Pentium
· PCI/EISA Board Gigabyte GA586-ID 90MHz Pentium (dual processor, one

· PCI ATI GUP 2M VRAM
· Adaptec 1742 EISA SCSI controller
· Soundblaster 16
· usual I/O
Everything under DOS AND Linux works perfectly. No problem
whatsoever. A VERY fast machine! BYTE Unix benchmarks place it about
the same as a Sun SuperSPARC-20 running Solaris 2.3. The PC is faster
for integer arithmetic and process stuff (including context
switching). The SPARC is faster for floating point and one of the
disk benchmarks.
8.23. kenf@clark.net with G/W 2000
He uses a Gateway 2000 with no problems, except the soundcard (which
one?). He is trading it in for a genuine soundblaster in hopes that
will help.
8.24. Joerg Wedeck (jw@peanuts.informatik.uni-tuebingen.de) / ESCOM
originaly buyed a 486 DX2/66 from ESCOM (which board?) with onboard
IDE and without (!) onboard NCR-SCSI-chip. ISA-adaptec 1542cf scsi-
controller instead spea v7 mercury lite (s3, PCI, 1MB), ISA-
Soundblaster-16, mitsumi-cdrom (the slower one). Everything except
the archive-streamer works with no problems. The spea-v7 works
perfectly since XFree86-2.1
He abandoned the Intel-board in favour of an ASUS-SP3-g and has some
problems with PCI-to-Memory burstmode which is crashing only on Linux,
"looking like a deadlock in the swapper". If you have any information
on this, please eMail the maintainer of the PCI-HOWTO.
After turning off the PCI-to-Memory posting feature it just works
perfect.
Rather than sending him mail please read his http-homepage at
"http://wsiserv.informatik.uni-tuebingen.de/ jw" where he keeps
information about his PCI-system, too.
8.25. Ulrich Teichert / ASUS
ASUS-PCI board with AMD486dx40 (but actually running at 33Mhz?!) His
ISA-ET3000 Optima 1024A ISA works nice. No problems with Quantum540S
SCSI Harddisk attached to the onboard NCR53c810.
9. Reports of problems
9.1. Compaq PCI systems, especially Presarios
Patrick Yaner (p_yaner@eos.ncsu.edu) reported a Compaq-speciality to
me. It seems they are mapping the PCI BIOS data area to an obscure
area of memory, one that Linux (or OS2) cannot access. It can usually
find it, but it can't get in, and gives a message on startup
(something like "pcibios_init: entry in high memory area, unable to
access"). Although this is alright with the display (which is on the
PCI bus) and the IDE controller (also PCI), it means any other PCI
devices -- such as an Ethernet card -- cannot be detected by Linux.
Compaq offers a driver for DOS at
ftp://ftp.compaq.com/pub/softpaq/Drivers/SP1116.ZIP
but using this with linux would mean using the program that boots
linux from DOS, instead of LILO. Note that Compaq occasionally
updates the software in this archive, so the file
ftp://ftp.compaq.com/pub/softpaq/allfiles.html (also available as
allfiles.txt) might be handy in checking to see that they haven't
upgraded.
Oddly, this information can also be found in the SCSI HOWTO, although
the Pressarios come with IDE built in.
9.2. VLSI Wildcat PCI chipset like in Zeos P120 box
Paul Bame (bame@sde.hp.com) reported:
The Wildcat PCI chipset works fine in late 1.3 and all 2.0 kernels.
9.3. dmarples@comms.eee.strathclyde.ac.uk G/W 2000
Gateway 2000 G/W 2000 4DX2/66 PCI ATI-Graphics-Ultra-Pro IDE of
indeterminate make
It works well - only the IDE-Card runs in ISA-compatibility-mode, and
works a lot faster when switched into PCI-Mode by a DOS-program...
thus it's not that fast in Linux, and a patch would be nice.
9.4. cip574@wpax01.physik.uni-wuerzburg.de (Frank Hofmann) / ASUS
He uses the ASUS-board with 16MB-RAM, ISA-based S3/928, and the
onboard-IDE-controller with a Seagate ST4550A harddisk. He's had no
trouble with the newer Linux-kernels.
His problem:
using X, my mouse is not responding the way I was used to before. It's
sometimes behind movement and makes jumps if moved quickly. I think
this was discussed In a Linux newsgroup before (I don't know which
one) and is due to the use of 16550 serial chips for the onboard
serial interfaces. After two weeks, I got used to it :-)
Reducing the threshold of the 16550 should help. There should be a
patch to setserial available somewhere, but I do not know where.
9.5. axel@avalanche.cs.tu-berlin.de (Axel Mahler) / ASUS
ASUS PCI/I-486SP3 Motherboard (Award BIOS 4.50), 16 MB RAM the on-
Board NCR Chip is disabled, he had the Genoa Phantom/W32 2MB for PCI
and a Adaptec AHA-1542CF (BIOS v2.01) connected to:
· an IBM 1.05 GB Harddisk
· a Toshiba CD-ROM (XM4101-B)
· a HP DAT-Streamer (2GB)
when creating the filesystems, 'mke2fs' (0.4, v. 1.11.93) hung and
installation was impossible. After replacing the Genoa Phantom/W32 2MB
PCI with an ELSA Winner 1000 2MB PCI it worked perfectly. He tested
it with an old Eizo VGA-ISA and it worked as well, so the problem was
in the Genoa-PCI-card.
9.6. Frank Strauss (strauss@dagoba.escape.de) / ASUS
ASUS SP3 Board i486DX2/66 NCR53c810 disabled Adaptec 1542B in ISA Slot
with 2 hard drives (200MB Maxtor, 420MB Fijutsu), SyQuest 88MB and
Tandberg Streamer ELSA Winner 1000 PCI, 1MB-VRAM Soundblaster Pro in
ISA Slot at IRQ 5 Onboard IDE disabled Onboard serial, parallel, FD
enabled
After a reset, the machine sometimes 'hangs' (soft and hard-reset the
same) - this is probably not related to the Adaptec and the Soundcard,
because even without these the system sometimes fails to come up. But
if it runs, (and the ELSA-WINNER-1000-PCI-message appears) it runs ok.
The two serial ports are detected as 16550 as they should, but at some
mailbox-sessions there was heavy data-loss at V42bis... The problem
seems to be in the hardware...
CPU>-PCI-Burst seems to work well with DOS/MS-Windows
CPU->PCI-Burst does not work properly with linux0.99p15, Messing up
when switching the virtual-consoles, crashing completely when calling
big apps like ghostview, or xdvi, leaving the SCSI-LED on (!).
(I suspect these apps would be using a lot of CPU->PCI-burst because
of the big heap of data to transmit to the PCI-Winner-1000)
After disabling CPU->PCI-Burst, it works well, the Winner-1000 at
1152x846 (not much font cache with 1MB) does 93k xstones. OpaqueMove
with twm is more than just endureable :-)
He has got a SATURN.EXE which he loads under DOS before starting
Linux, helping to turn on burst without hangs...
Someone stated that these problems might go away when turning off
"sync negotiation" on the Adaptec - I do not know if this is possible
with the adaptec1542B too? But I guess so.
With CPU->PCI-Burst it yielded 95k xstones, so he considers it as not
too grave to do without. His only problem is that he would like to run
his Winner-1000 at 1152x900 which fails because it seems to take any
x-resolution higher than 1024pixels as a 1280pixel-resolution, thus
wasting a lot end resulting in a y-resolution of 816pixels... but this
is probably no PCI-related problem. It should have gone away with
XFree86-2.1
9.7. egooch@mc.com / ASUS
· BOARD ASUS PCI/I-486 SP3 RAM: 16MB (4x4M-SIMM)
· CPU 486DX33 CPU
· BIOS Ver. 4.50 (12/30/93)
· Floppy Two floppy drives (1.2 and 1.44), using ASUS on-
board floppy controller
· SCSI tried both WD7000 SCSI controller and Adaptec 1542CF and
worked.
· Two SCSI 320M hard drives
· SCSI NEC84 CDROM drive
· SCSI QIC150 Archive tape drive
· Video - Tseng ET4000 ISA graphics card
· Sound PAS16 sound card
· Printer attached to on-board ASUS parallel port
He has nothing in the PCI-Slots yet, but wants to buy a PCI-Video-
Card, currently uses WD7000 SCSI controller but will switch to the
NCR-Chip onboard as soon as the driver is out.
Everything works perfectly - the first serial port which has a 14.4K-
Modem attached does hang occasionally when reconnecting with the modem
after having used it previously. He says that would not be unique to
ASUS but rather a bug in the SMC-LSI device with its 16550UART. The
logitech-serial-mouse on the second port works fine. Setting down the
threshold of the 16550 for the mouseport would definitely help, one
does seem to need a special patched setserial for that? I have not got
the information yet, please contact me if you know more!
9.8. Stefan.Dalibor@informatik.uni-erlangen.de / GigaByte
· Board - GA-486iS from Gigabyte w/ 256Kb 2L-Cache, i486-DX2
· Bios - AMI, 93/8
· SCSI - no scsi-NCR-chip on-board, using Adaptec 1542C,
· Video - ELSA Winner 1000
· Linux 0.99pl14 + SCSI-Clustering-Patches / Slackware 1.1.1
All seems to go well, but he has not tried neither networking,
printing or a streamer yet. Before applying the clustering- patches he
had some problems with hangs triggered by "find", but this no longer
is the case - perhaps it was an older kernel-bug.
The ELSA-Winner-1000 sometimes hangs, with very strange patterns on
the screen resolved only by rebooting... The dealer has told him it
was a bug in the ELSA-Card, but the manufacturer claims it had solved
the problem. The bug is not reproducible so he does not plan to take
any action at the moment.
All in all the machine seems to work very well under heavy text
processing (emacs, LaTeX, xfig, ghostview) usage. Interaction is
surprisingly responsive, little difference between it and the 3-4X as
expensive Sun he works on...
CPU->PCI-Burst is still disabled because the bios does not support the
PCI-things well?
A problem with his new modem (v32 terbo) arose: it looses characters.
Especially when using SLIP it complains a lot about RX and TX errors.
As soon as he runs X it gets unusable. He said he activated FIFO and
RTS/CTS with stty, but to no avail...
9.9. Steve Durst (sdurst@burns.rl.af.mil) with UMC 8500 mainboard
Running Linux 1.2.12 on the UMC8500-100Mhz motherboard with the
dreaded CMD PCIO640B (E)IDE controller, when booting the screen
wiggles a few seconds, as if the Diamond Stealth64-DRAM (S3 864) has
to warm up first, but he can live with that.
9.10. Tom Drabenstott (tldraben@Teleport.Com) with Comtrade / PCI48IX
PCI48IX Motherboard Rev. 1.0. Made by ??? documentation copyrighted by
"exrc". The BIOS says not very much about PCI.
His E-315E Super IDE UMC (863+865) ISA-Controller-card does have
problems. (It is a multifunction controller-card). It seems to work
well under DOS/OS2 but not under Linux.
10. General tips for PCI-Motherboard + Linux NCR PCI SCSI
This was compiled by Angelo Haritsis (ah@doc.ic.ac.uk) from various
people's postings:
10.1. DON'Ts:
Do *NOT* go for combination VLB/PCI motherboards. They usually have a
lot of problems. Get a plain PCI version (with ISA slots as well of
course). A lot of bad things have been heard about OPTI chipset PCI
motherboards. Someone hints: "Avoid the OPTi (82C596/82C597/82C822)
chipset based motherboards like the TMC PCI54PV".
(I know of at least one person having no problems with his TMC PCI54PV
motherboard. He just had to put the NCR53c810 addonboard into slot-A
which is the only slot capable of busmastering as it seems.)
Rumours say that Intel chipset PCI motherboards will have problems
with more than one bus-mastering PCI board. I have not tried this one
yet on mine and have nothing to suggest. I also heard that the Saturn
II chipset is problematic, but this is the one I use and it is
perfectly ok! Advice: Try to negotiate a 1-2 week money back agreement
with your supplier, in case the motherboard you get has problems with
the use you plan for it.
10.2. SIMM slots
Go for 72-pin only SIMMs for speed: Some (all?) of the mainboards
which take 30 pin SIMMs use a 32 bit main memory interface, and will
be significantly slower than the Intel based boards which all use a 64
bit or permantly interleaved memory interface. You might want to keep
that in mind.
10.3. Praised PCI Pentium motherboard
The P90 Intel motherboard with the Intel Premiere II chipset (aka
Plato). Get the latest BIOS which has concatenated NCR scsi BIOS
3.04.00. Otherwise DOS won't see your scsi disk(s) if you use a BIOS-
less 53c810 based controller. NCR SCSI BIOS exists in the AMI BIOS of
the plato after version 1.00.08 (or maybe verion 1.00.06). This BIOS
is FLASH upgradeable so you should be able to get the upgrade on a
floppy from your supplier. The current version is 1.00.10 and has all
early problems fixed.
(Bios files should be available at ftp.demon.co.uk:/pub/ibmpc/intel,
but I did not check that myself. the Autor.)
10.4. irq-lines
The value in the interrupt line PCI configuration register is usually
set manually (for compatability with legacy ISA boards) in the
extended CMOS setup screens on a per-slot or per-device basis. Older
PCI mainboards also force you to set jumpers for each PCI slot/device
which select how PCI INTA and perhaps INTB, INTC, and INTD are mapped
to an 8259 IRQ line, Obviously, if these jumpers exist on your board,
they must match the settings in the extended CMOS setup. Also note
that some boards (notably Viglens) have silkscreens and instruction
manuals which disagree with the wiring, and some experimentation may
be in order.
10.5. Info about the different NCR 8xx family scsi chips:
All NCR 8XX Chips are dircet connect PCI bus mastering devices, that
have no preformance difference wether on motherboard or add in option
card. All devices comply with PCI 2.0 Specification, and can burst 32
bit data at the full 33 MHz (133Mbytes/Sec)
10.5.1. 53C810
53C810 = 8 bit Fast SCSI-2 (10 MB/Sec) Single ended only Requires
Integrated Mother board BIOS 100 pin Quad Flat Pack (PQFP) Worlds
first PCI SCSI Chip, Volumes make it the most inexpensive.
10.5.2. 53C815
53C815 = 8 bit Fast SCSI-2 (10 MB/Sec) Single Ended only Support ROM
BIOS interface, which makes it ideal for add-in card Designs. 128 Pin
QFP
10.5.3. 53C825
53C825 = 8 bit Fast SCSI-2, Single ended or Differential 16 bit Fast
SCSI-2 (20 MB/Sec), Single ended or Differetial Also has support for
external Rom, making it a good candidate for add in cards. 160 pin QFP
Not supported by linux yet. (See section below on news about the 825).
Must have devices with wide or differential scsi to use these
features.
10.6. future of 53c8xx
There are 4 new devices planned for announcement late this year and
into early next year. Footprint compitible with 810 and 825 with some
new features.
All the Chips require a BIOS in DOS/Intel applications. The 810 is
the only chip that needs it resident on the motherboard. Latest NCR
SCSI BIOS version: 3.04.00 The bios supports disks >1GB, indeed up to
8G under MS-LOSS.
10.7. Performance of the 53c810
C't magazine's DOS benchmarks showed that it was significantly faster
than the Buslogic BT-946, one user noted a 10-15% performance increase
versus an Adaptec 2940, and with a very fast disk it may be 2.5X as
fast as an Adaptec 1540.
10.8. News about NCR53c825 support
works. period.
10.9. Frederic POTTER (Frederic.Potter@masi.ibp.fr) about Pen­
tium+NCR+Strap_bug
On some Intel Plato board, the NCR bios doesn't recognize the board,
because it needs to see the board as a "secondary SCSI controller",
and because on most SCSI board the jumper to select between
primary/secondary has been ironed to primary (to spare 1 cent,
presumably).
Solution:
near the NCR chip, they are 3 via ( kind of holes ) with a strap like
that
O--O O
this mean primary is selected as default setting. For the Plato Intel
Mainboard, it should be like that
O O--O
The best solution is to get rid of the strap and to put a 2 position
jumper instead.
10.10. PCIprobe in the latest Linux Kernels by Frederic Potter
Frederic Potter has added a PCI-Probe into the latest kernels. If you
do a "cat /proc/pci" it should list all your cards. If you own cards
which are not properly recogniced, please contact him via mail as
"Frederic.Potter@masi.ibp.fr".
See arch/i386/kernel/bios32.c and include/linux/pci.h in the kernel
source for more information on PCI-Probe-Stuff.
10.11. Other PCI Devices
What other PCI-cards are supported? Apart from various graphicscards,
I would like to know about other cards like ethernet, framegrabber, or
the TSET boards Cyclades is about to beta-test at the moment:
10.11.1. Cyclades: a 16-port PCI RISC-based multiport card.
The product is called Cyclom-Ye, and has the following
characteristics:
· PCI host card based on the PLX chip-set. This host card supports 8
to 32 serial ports, utilizing 8 or 16-port external boxes.
· SCSI II cable.
· 8 or 16-port external boxes with RJ45 or DB25 connectors (your
choice). You can start with 8 ports and expand to 32, by just
adding more boxes. Each external box contains 2 or 4 CD-1400 RISC
Serial controllers (each CD-1400 controls 4 serial ports).
· Up to 4 Host cards can be installed in the PC system, allowing a
maximum of 128 serial ports per system.
The product is being in the beta-test phase at July the 26th, 1995,
and should be available by Octobre or something. eMail them at

11. Conclusion
If you have some moneny to put into your machine, you'd be well off
with a Pentium90, ASUS-SP4, which is what I use at the moment. If you
can afford 32M RAM that would be much better than 16M RAM.
Real soon now the upcoming standard will be the Triton Chipset with
support for special SIMMS called EDODRAM, and SRAM. Both will be more
expensive than PS2-RAM, and at the time of writing (28-June-1995) SRAM
is not available. While EDO-DRAM is more expensive, this is not
because of the production costs, they are said to be the same.
For a highperformance system I would still choose an ASUS-TP4/XE with
EDO-DRAM, but if you do not need to use it at the moment, I d rather
wait some more.
For Graphic-boards I'd say the best cheap board fitting perfectly on a
good Multisync-15 like the Samsung SyncMaster 15Gli, is the SPEA V7
Mirage P64 with Trio64 Chipset and 2M DRAM. For more sophisticated
Display like the Iiyama-IDEK 8617A-T I think the PCI Mach64 ATI-GUP-
Turbo (not the cheaper GUP-Turbo-Windows) would be a good choice, with
4M RAM you can have truecolor in higher resolutions. It is well
supported in the XFree86(tm)-3.1.1, and there are commercial X-Servers
available of which I'd recommend Accelerated/X by Roell, which
supports the Mach64 very well and fast.
For SCSI I'd take the DPT rather than the (much cheaper and very fast)
NCR53c810 in case you plan to use SCSI-Tapes a lot. The NCR53c810
driver on Linux does lack disconnect/reconnect support, thus blocking
the SCSIbus on operations like "mt rewind", "mt fsf" etc. It bears a
performance penalty on tar-operations - but check out Drews new alpha
drivers before making a decision, perhaps it does solve all the
problems.
For building servers, the DPT would be the controller of choice anyway
because of all the nifty hardware cache (with elevator sorting on
accesses, so cache it is not a silly thing even in a Linux enviroment
where the OS does the caching) and RAID-Support up to raid level 5.
If you do not want to spend that much money on computer equipment
(e.g.: you are having a life) you might go for an ASUS-SP3-SiS with
AMD-DX2/66 or DX4/100. The SPEA V7 Mirage P64 PCI with 2M DRAM would
be a good choice, since it uses the Trio64 S3 Chip, which is well
supported by XFree86(tm)-3.1.1, quite cheap to buy and fast, too.
Another fine card since XFree86(tm)-3.1 is the fast and cheap
et4000/w32-PCI-card.

14. GPL - Gnu Public License
GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy (name of author)
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.
